Valve of inferior vena cava


The valve of the inferior vena cava (eustachian valve) is a venous valve that lies at the junction of the inferior vena cava and right atrium. In prenatal development, the eustachian valve helps direct the flow of oxygen-rich blood through the right atrium into the left atrium and away from the right ventricle.

The eustachian valve (also known as the "valve of the inferior vena cava") is a ridge of variable thickness in the inferior right atrium. It is a remnant of a fetal structure that directed incoming oxygenated blood to the foramen ovale and away from the right atrium.

The inferior vena cava, larger than the superior, returns the blood from the lower half of the body, and opens into the lowest part of the atrium, near the atrial septum, its orifice (Opening of inferior vena cava) being directed upward and backward, and guarded by a rudimentary valve, the valve of the...

The inferior vena cava (IVC) is the largest vein in the body. It runs alongside the abdominal aorta, but there are several important differences between their branches and tributaries which make perfect fodder for trick questions in exams! I hope you find this anatomy guide helpful.

The inferior vena cava is a large vein that carries blood that circulated in the lower half of the body back to the heart. But the anatomy of the IVC vein is slightly different. Instead of valves, the pressure from breathing and the contraction of the diaphragm as the lungs fill with air helps to pull the blood...

The inferior vena cava is a large vein in the middle of your body. The device is put in during a short surgery. The veins in your legs have tiny valves that help keep blood moving back up toward the heart. But a DVT may damage one or more of these valves.

The superior vena cava and inferior vena cava are the two largest veins in the body. Veins in the legs and arms also have valves in the innermost layer that are formed from the infolding of Superior vena cava syndrome is a serious condition that arises from the constriction or obstruction of this vein.

The inferior vena cava is also referred to as the posterior vena cava. The inferior vena cava is a large vein that carries de-oxygenated blood from the lower body to the heart.

Inferior vena cava (IVC) diameter and respirophasic variation are commonly used echocardiographic indices to estimate right atrial pressure. While dilatation of the IVC and reduced collapsibility have traditionally been associated with elevated right heart filling pressures...

The inferior vena cava is formed by the coming together of the two major veins from the legs, the common iliac veins, at the level of the fifth lumbar vertebra, just below the small of the back. Unlike the superior vena cava, it has a substantial number of tributaries between its point of origin and its...

Defecation syncope secondary to functional inferior vena caval obstruction during a Valsalva maneuver. In the embryo, the IVC and right atrium are separated by the Eustachian valve, also known in Latin as the "valvula venae cavae inferiore" (valve of the inferior vena cava).

Thrombosis of the inferior vena cava (IVC) is an underrecognized entity with a variety of clinical presentations. No valves are within the IVC. The cava enters the thoracic cavity through the tendinous portion of the diaphragm and terminates at its junction with the right atrium.

Inferior Vena Cava Thrombosis or Occlusion. IVC thrombosis may result from innate thrombogenicity of the filter, trapped emboli within the filter, or propagation of thrombus through the venous system up to and including the filter (see Figure 47.2).

The superior vena cava is classified as a large vein, with a wide diameter of up to 2cm and a length of approximately 7cm. It arises from the union of the left and right brachiocephalic veins, posterior to the first right costal cartilage. It descends vertically through the superior mediastinum...

The inferior vena cava is the largest vein in your body. It carries blood from your lower body to your heart and lungs. A blood clot in a vein below your heart blocks your normal blood flow and may cause swelling, redness, and pain in the area. Blood clots are treated with blood thinners but some people...

The valve of the inferior vena cava (eustachian valve) is a venous valve that lies at the junction of the inferior vena cava and right atrium. In prenatalThe inferior vena cava (or IVC) is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heartsituated at the base of the inferior vena cava. The valve may vary in size, or be completely absent. It may prevent the regurgitation of blood into the sinustricuspid valve and the pulmonary valve are in the right heart. The heart also has a coronary sinus valve, and an inferior vena cava valve, not discussedSuperior vena cava syndrome (SVCS), is a group of symptoms caused by obstruction of the superior vena cava ("SVC"), a short, wide vessel carrying circulatingdiaphragm, flows through the inferior vena cava. The SVC is located in the anterior right superior mediastinum. It is the typical site of central venous accessatrium receives and holds deoxygenated blood from the superior vena cava, inferior vena cava, anterior cardiac veins and smallest cardiac veins and the coronaryfrom the front of the superior vena cava to the front of the inferior vena cava, and represents the line of union of the sinus venosus of the embryo withThe aortic valve is a valve in the human heart between the left ventricle and the aorta. It is one of the two semilunar valves of the heart, the othermade up of elastin and endothelial cells.[citation needed] The tendon of Todaro is a continuation of the Eustachian valve of the inferior vena cava and theand pulmonary trunk leave the heart and where the superior vena cava, inferior vena cava and pulmonary veins enter the heart. In between the parietal(LCA) arises from the aorta within the left cusp of the aortic valve and feeds blood to the left side of the heart. It branches into two arteries, the leftthree aortic sinuses (dilations) in the wall of the aorta just superior to the aortic semilunar valve. Two of these, the left posterior aortic sinus andof the right atrium. If the aneurysm stretches too far, it can narrow the opening of the inferior vena cava. This type of aneurysm can be a result ofpulmonary trunk , and anterior to the superior vena cava.

The Purkinje fibers are specialised conducting fibers composed of electricallythe right atrium and into the inferior vena cava. In some operations, such as those involving the tricuspid or mitral valve, two cannula are used—one istravels inferiorly separating the left atrium and left ventricle. The location of the left coronary sulcus is marked by the circumflex branch of left coronaryhearts. It involves diverting the venous blood from the inferior vena cava (IVC) and superior vena cava (SVC) to the pulmonary arteries without passing throughmuscles that holds chordae tendinae, which are connected to cusps of valves to control flow of blood into the heart Trabeculae lie at the interface betweenof smaller ones.
